Protect Structural Investments with Stainless-Steel Connections

The Science Behind Simpson Strong-Tie Stainless Steel ConnectorsEach Simpson Strong Tie® stainless steel connector is made with type 316L stainless steel. Because stainless steel contains nickel and chromium, stainless steel develops a thin layer of chromium oxide on the surface of the metal that protects the connector from corrosive attack. Type 316L stainless steel also includes molybdenum, which helps increase corrosion resistance chloride type areas, such as salt water environments. Type 316L has shown no visible sign of surface red rust after 1,000 hours of an ASTM B117 salt spray test. For more information about corrosion, visit www.strongtie.com/info.

A Superior Level of ProtectionWhen choosing structural connectors for a project, it is important to consider the long-term effects of corrosion. Simpson Strong-Tie® offers a broad variety of stainless-steel connectors designed to provide a superior level of protection and durability against corrosive environments and materials.

Metal fasteners and anchors will corrode and may lose load carrying capacity when installed in corrosive environments or exposed to corrosive elements. There are a number of factors and environments that can negatively affect structural connections including:

U.S.A. joist hanger shown, not available in New Zealand or Australia

Provides a high-strength connection between the post and concrete. Designed to install on hardened concrete with either a cast-in-place or post-installed anchor, the ABU is designed to provide maximum uplift performance for areas where uplift from high winds is a concern.

Key Features

• Slotted base enables flexible positioning around the anchor bolt, making precise post placement easier

• 25 mm standoff helps prevent rot at the end of the post in applications where weather or moisture are present

• Post can be fastened with either nails, bolts or Strong-Drive® SD Connector screws

Stainless Steel Timber Connectors

ABU Adjustable Post Base with Standoff1.

Provides a clean, concealed look whilst providing a 25mm standoff above the concrete. This reduces potential for decay at the post end.

• Tested and load-rated for uplift and lateral load

• Anchorage can be cast-in-place or retrofitted with mechanical or adhesive anchors

Complete the Connection

Always use stainless-steel fasteners

with stainless-steel connectors.

Even with the protection of

stainless-steel connections,

structures in corrosive environments

can be compromised over time

when these connectors are installed

with fasteners that are not stainless

steel. Carbon-steel fasteners

with coatings such as hot-dip

galvanisation will corrode faster

than the stainless-steel connectors

that they fasten. This can create a

weak link that can eventually lead

to failure. Likewise, fasteners made

from a lower grade of stainless steel

can also corrode at a faster rate

than our type 316L stainless-steel

connectors. Type 316 stainless-steel

nails or screws protect the integrity

of the structure and the investment

made in stainless-steel connectors.

Simpson Strong-Tie offers type

316 stainless-steel nails and

Strong-Drive SDS screws that fasten

our stainless-steel connectors.

Offers a versatile, concealed connection between the stair stringer and the carrying header or rim joist while replacing costly framing. Field slopeable to all common stair-stringer pitches, the LSC connector is suitable for either solid or notched stringers.

Key Features• Replaces additional framing and

toenailing and may be installed flush with the top of the carrying member or lower on the face.

• Suitable for most installations on 45 x 250 mm or 45 x 300 mm header/rim joist.

LSCSS Adjustable Stair-Stringer Connector8.

Provide a positive connection between the truss/rafter and the wall of the structure to resist wind and seismic forces.

Key Features

• The H2.5A and H3 connects the truss/rafter to the top plate

Make it easier to build structurally sound stairs.

Key Features• Installing stair treads with TA

angles instead of notching the stringers saves time and results in a full cross-section stringer.

• Installs easily with Strong-Drive® SDS Heavy-Duty Connector screws; no pre-drilling required.

Correct ledger attachment is crucial when building a deck that is attached to another structure. One of the most common causes for deck failure are ledgers that pull away from the primary structure, resulting in complete collapse.

The SDS provide an easy-to-install, high-strength alternative to lag screws and through-bolts
